Application May 25, 1948, Serial No. 29,041

3 Claims.

My invention relates particularly to brushes adapted for the rapid and efficient removal of incrustations and clogging matter from conduits and tubes, such as drain, waste and sewer pipes and has for its principal objects, to generally improve upon and simplify the construction of existing forms of pipe and tube cleanout brushes, to provide a brush having a plurality of radially disposed tufts or resilient wire bristles and to mount such tufts in the brush body so that they will flex readily in use, with minimum possibility of breakage of the individual bristles at the point where they are connected to said body.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed and illustrated in the accompanying drawing, in which:

Fig. 1 is a front end view of my improved brush.

Fig. 2 is an enlarged vertical longitudinal section taken on the line 2--2 of Fig. 1.

Fig. 3 is a cross section on the line 33 of Fig. 2.

Fig. 4 is a cross section on the line 44 of Fig. 2.

Referring by numerals to the accompanying drawings which illustrate a preferred embodiment of my invention, In designates the rear member of the brush body which is tubular in form with its rear end internally threaded for reception of a tubular handle, or the end of a flexible tube ll of coiled wire and which is generally referred to as a snake.

The forward end of member ID is externally threaded and provided with a plurality of short longitudinally disposed slots I2.

Formed at the inner ends of slots [2 is an annular rounded shoulder 'I 3 which serves as a bearing for the looped central portions of the wire bristles of the brush.

The forward member of the brush body comprises a short forwardly tapered body M having its rear end internally threaded so as to be screw seated on the threaded forward end 0f body member l0 and extending forwardly from the rear end of said forward member is an axial bore IS in which is seated an expansion coil spring It.

The tufts of bristles I! used in my improved brush are each formed from a plurality of sections of resilient wire, the central portions of which are looped around a ring l8 and thus, when the tuft z:

nr Ll carrying ring is inserted in the slotted forward end of member I 0, one tuft projects through each slot I2, with the looped inner ends of the tufts bearing on shoulder 13 (see Fig. 2).

To yieldingly maintain the looped portions of the tuft forming wires against shoulders I3, a metal ball I9 is, under the expansive forces of spring I6, pressed against the front sides of the looped portions of the tuft forming wires.

In use, the brush by means of its handle, is insorted into and reciprooated within the conduit to be cleaned and as a result of such action, the ends of the tuft will effectively scratch, cut and scrape the inner surface of the conduit to cut, :disintegrate and thereb loosen and remove all incrustations from said surface and such action may also be followed in removing clogging bodies of earth, sand or other waste matter.

If desired or necessary, the conduit cleaning functions may be accelerated by delivering water under pressure, through the tubular handle and thereby produce jets which discharge through slots l2.

In addition to cleaning waste, drain and sewer pipes, my improved brush may be advantageously used in cleaning the tubes and flues of boilers and the like.

Thus it will be seen that I have provided a pipe and tube cleanout brush that is simple in structure, inexpensive of manufacture and very effective in per-forming the functions for which it is intended.

Various minor changes in the size, form and construction of the various parts of my improved cleanout brush may be made and substituted for those herein shown and described, without departing from the spirit of the invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. In a pipe and tube cleanout brush, a hollow body provided in the forward portion of its wall,

with longitudinal slots, tufts of bristles having, their inner ends loosely seated in said body and projecting outwardly through said slots, a, ring on which the inner ends of the tufts of bristles are mounted, a nose piece removabl mounted on theforward end of said body and yielding press-uremeans within said nosepiece and bearing on theends of said bristle tufts within said body.

2. The pipe cleanout brush as set forth in claim 3 1, and which yielding pressure means comprises a spring pressed ball.

3. A pipe cleanout brush comprising a. tubular body provided in its forward end with short longitudinally disposed slots, a ring within the slotted portion of said tubular body, tuft-s of wire bristles looped about said ring and projecting outwardly through said slots, rounded shoulders at the inner ends of said slots for the inner ends of said tufts of bristles and a spring pressed ball bearing on the inner ends of said tufts of lbristles on the opposite sides thereo from said shoulders.
